You are making a lot of assumptions in your post. Have you questioned any of them? How much it costs to set up a system to avoid tax? How tax havens actually came about? How corporates actually use them? The information is out there and there's at least one good book on the subject (Treasure Islands by Nick Shaxon).

Yes, Google has to pay an army of both lawyers and accountants to take care of all the crazy complex tax scheme internationally. I know several people who run startups with such schemes and they give 1% of their revenue to their accountant. If we got rid of the IRS and equivalent and just used a flat tax on the total amount of revenue, well, let's say the CPA industry would take a plunge and regular folks and companies like Google would save billions.
